Don't even attempt to remove the nosedrive by itself. You'll get pissed and push the car off the cliff.
Get the supercharger outlet gasket, TB gasket, and anything else you want from the dealer, and get the coupler from www.zzperformance.com
I suggest reading ALOT here in Forced Induction before you begin. Especially the sticky post up at the top of the forum, and do a search on "rebuild" or "coupler" in Forced Induction.
Torque specs are in Techinfo, Specifications at the top of the page, but I still strongly suggest a service manual of some type.
